Question Discussion & Solution

1. Three friends, Vinitha, Mira and Neethu, had lunch at a hotel.

2. When the bill was received, Vinitha paid 2/3 as much as Mira paid and Mira paid 1/2 as much as Neethu paid.

Vinitha = Mira       ---(i)

Mira =  Neethu

2 Mira = Neethu       ---(ii)

As, the total bill was divided among them

So, Vinitha + Mira + Neethu = 1       ---(iii)

Substituting the value of (i) and (ii) in (iii), we get:

Mira + Mira + 2 Mira = 1

Mira = 3/11

Flood is overflow of water. In the same way, drought is a continuous dry period of weather.

The correct answer is option 4) i.e. All of the above

CONCEPT:

• Magnetic field: The region around a magnet where its influence is experienced is called the magnetic field.
  • The visual representation of the magnetic field is called magnetic field lines.

​

• ​Properties of magnetic field lines:
  1. ​​The field lines start from the north pole and end at the south pole.
  2. The field lines are crowded where the magnetic field is the strongest.
  3. The field lines form continuous curves.
  4. The field lines do not intersect.

EXPLANATION:

• The magnetic field is strongest near the poles. Since magnetic field lines start and end at poles, they converge towards the region of strong magnetic force.
• Two magnetic field lines cannot intersect. If they did, at the point of intersection, the magnetic field will have two directions - which is not possible.
• The magnetic field lines have direction as they are represented as flowing, though no actual movement occurs. So, they do not move.

Therefore, all the given statements are true.
